Feeding the skin from the inside out

Skin ageing is a process in which both environmental and intrinsic factors lead progressively to a loss of structural integrity and physiological function. Intrinsic structural changes occur as a natural consequence and are genetically determined. For example, collagen levels start declining in the mid 20s. Intrinsic ageing is characterised by three main dermal factors: atrophy of dermis due to loss of collagen, degeneration in the elastic fibre network, and loss of hydration. These structural changes result in visible signs of ageing such as wrinkles, loss of firmness and elasticity. Environmental stressors such as UV radiation or toxic air pollution, as well as stress in one’s life accelerate this process.
